Practice and master Python sets with interactive fill-in-the-blanks exercises. Strengthen your understanding of set operations, membership, and manipulation. Ideal for beginners and students learning Python.
Topic: sets
set()
Empty curly braces {} create an empty dictionary, so set() must be used to create an empty set.
clear()
clear() is the method that empties a set without deleting the set object itself.
pop()
pop() removes and returns a random element from the set, useful when you need to process elements.
|
The | operator combines elements from both sets, similar to the union() method.
symmetric_difference
symmetric_difference() or the ^ operator gives elements that are in exactly one of the sets.
frozenset
frozenset is hashable and immutable, making it suitable as a dictionary key unlike regular sets.
update()
update() modifies the original set by adding elements from another set or iterable.
discard()
discard() safely removes an element if present, unlike remove() which raises KeyError if missing.
curly
Set comprehensions use {} (curly braces) similar to dictionary comprehensions but without key-value pairs.
issubset()
issubset() or <= checks if all elements of one set are contained in another set.
